• Integer variable is acquiring a string value of "ad" somewhere along the line, can anyone see where?

  - by Phil

  Here is my code: I should get output of the department id (did) as an integer and the templatefilename (result) that is required. The errors I get are: Conversion from string "ad" to type 'Integer' is not valid. I'm fairly new to asp.net and cannot see where the did variable picks up the "ad" string. Any help would be greatly appreciated. Thanks

• How can fill a variable of my own created data type within Oracle PL/SQL?

  - by Frankie Simon

  In Oracle I've created a data type: TABLE of VARCHAR2(200) I want to have a variable of this type within a Stored Procedure (defined locally, not as an actual table in the DB) and fill it with data. Some online samples show how I'd use my type if it was filled and passed as a parameter to the stored procedure: SELECT column_value currVal FROM table(pMyPassedParameter) However what I want is to fill it during the PL/SQL code itself, with INSERT statements. Anyone knows the syntax of this?

  I am curious if there is any history behind why the ^ character is used to escape the special characters <, , |, &, and ^ in environment variable names in Windows instead the '\' character that is typically used to escape special characters. Please note that I realize there may be no reason for this, but I'd be interested to hear if there is a reason.

• Reusing a NSString variable - does it cause a memory leak?

  - by Chris S

  Coming from a .NET background I'm use to reusing string variables for storage, so is the code below likely to cause a memory leak? The code is targeting OS X on the iphone/itouch so no automatic GC. -(NSString*) stringExample { NSString *result = @"example"; result = [result stringByAppendingString:@" test"]; // where does "example" go? return result; } What confuses me is an NSStrings are immutable, but you can reuse an 'immutable' variable with no problem.

• Most inappropriate function or variable names you have encountered?

  - by Andrioid

  I was reading through my daily doze of RSS when I noticed a link to the python compiler documentation where class names like assList, assName and assTuple exist. While starting names with 'ass' is perfectly acceptable to me, it just sparked this idea that there probably exist much better examples of this. Have you personally used or otherwise encountered any inappropriate function or variable names? Personally I have used 'crap' and 'moo' for temporary purposes, forgot them and at a later point they came too integrated for me to bother with fixing them.

• A more elegant way to parse a string with ruby regular expression using variable grouping?

  - by i0n

  At the moment I have a regular expression that looks like this: ^(cat|dog|bird){1}(cat|dog|bird)?(cat|dog|bird)?$ It matches at least 1, and at most 3 instances of a long list of words and makes the matching words for each group available via the corresponding variable. Is there a way to revise this so that I can return the result for each word in the string without specifying the number of groups beforehand? ^(cat|dog|bird)+$ works but only returns the last match separately , because there is only one group.
